The above chart is a generic trend line for the seasonally and non-seasonally adjusted 20-City Case Shiller Index released today using the data from the release.

And here’s the same index that I time-shifted backwards by 6 months to reflect the “meeting of the minds” of buyers and sellers. More specific methodology is embedded in the following charts. By moving the index back 6 months, the changes in the direction of the index are in sync with economic events (reality). In my view this index has a 6 month (5-7) month lag rendering it basically worthless to consumers but perhaps a useful tool for academic research where timing may not be as critical. I’m just grasping here.

And here’s a time-shifted trend line for the year-over-year change in the 20 city index. You can see that the pace of year-over-year price growth began to cool at the end of last year. Talk about the weather is still premature since the polar vortex occurred after the new year.

And here is the ranking by year-over-year changes for each city as well as the 10 and 20 city index. Dallas and Denver are no longer under water and Las Vegas, despite recent good news has a long way to go to get to the artificial credit induced high it reached in 2006.

Of course inventory has been near historic lows for a few years so that’s not a new reason. I’m left with the weather and as someone who hates to use the weather as a crutch, it seems to be a pragmatic – it’s difficult to show or be in the mood to view properties when it is zero degrees outside. The weather explanation was also used in the prior report but those contracts were signed in December for the January report, before the “polar vortex.”

I see the recent fretting about the cooling of housing as an indication of how improving conditions were based largely on Fed policy and not fundamentals. The combination of rising mortgage rates and declines from the year ago release of pent-up demand post-“fiscal cliff” likely gets price gains and sales levels in sync with fundamental economic conditions.

I’ve charted NAR EHS stats from the past 4 years without seasonal adjustments. Price gains have been insane so the combination of slowing sales and rising inventory will take the froth out of the market and hopefully get us on a more sustainable path.

Jed Kolko does a nice job summarizing what the general housing market may look like in 2014 after the new home sales report came out today.

My big takeaway was that any housing market improvement will be more affected by local job and income growth rather than the “rebound effect.” This phenomena occurred in markets that were hit hardest by the downturn, yet saw the largest price increases.

Back in early January, the US experienced what has now become a household phrase – “The Polar Vortex” and extreme weather has morphed its way into recent housing reports as plausible explanations for a slow down in some of the results.

Buyer perspective: Imagine a couple looking to buy their first home and decide they will begin looking right after the New Year. The dreaded Polar Vortex hits and it is too uncomfortable to run around looking at houses in freezing temperatures, so they postpone until the weather warms up in a month or 2.

Seller perspective: Imagine a homeowner who decides to put their home on the market and they experience searing pain from the cold by simply going to the grocery store. They can’t imagine a buyer coming to look at their home in the severe weather and don’t want their home to sit, so they postpone until the weather warms up in a month or 2.

In both scenarios, I would venture to guess that no one would say:

WOW, this weather is severe. I’ve rethought my (buying or selling) decision and will cancel the idea for a few years because the weather is too cold right now.

or

WOW, this weather is severe. Staying warm in my home right now made me realize that I rushed to make my decision and will no longer (buy or sell) for a long time.

Consumers can better relate to the weather than macro economic theory so throw it into the title of a news article:

If we isolate the housing market to new construction (which represent about 15% of sales historically) then it gets a lot more plausible – ie permits, starts etc. can be more affected by the weather on a pragmatic basis.

But that has little or no impact to the vast majority of housing consumers.

Here’s one way to visualize the potential impact of weather to retail sales activity (translation: slow down, spring back) in Business Insider.
